CHARLES P. VAN GUNDY, OF CATONSVILLE, MARYLAND, ASSIGNOR TO KENNICOTT WATER- SOFTENER COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS.

WATER-PURIFYING- APPARATUS.

To all 'whom it may concern:

Be it known that I, CHAnLns P. VAN GUNDY, a citizen of the United States, residing at Catonsville, in the county of Baltimore and State of Maryland, have invented certain new and useful Improvements in Nater-Purifying Apparatus, of which the following is a specification.

My invention relates to water purifying apparatus of the type wherein a determinate quantity of chemical is .introduced into the water so that the impurities therein are precipitated or neutralized according to the result desired and chemicals used.

The invention consists in an improved device whereby the amount of chemical introduced is varied according to the variations in the water supply.

My invention will be understood from the following description taken in connection with the accompanying drawing in which similar reference characters indicate the same parts in the several 'figures of drawing and wherein Figure 1, is a central vertical section showing my improved apparatus, mounted on the top of a settling tank; Fig. 2, is an enlarged end view of the adjustable outilow opening of the water reservoir; Fig. 3, is a similar view of the tilting chemical feed box.

1il designates a settling tank equipped in any suitable manner with flushing valves, iilter and overflow and having in the present instance a central pipe 2a therein which may have suitable openings into the tank in the lower part thereof (not shown). The tank la may have overflow 3 and a filter 4a of excelsior or the like. A suitable perforated baille 5at and a conical funnel 6a may be provided at the top of said pipe 2tL for the admis sion of water thereinto. Supported over the top of the tank lCL and securely held on each side of the central pipe 2u are I-beams 2b. The water supply pipe 7, delivers into a reservoir 8, said reservoir being mounted on the I-beams so that its overflow or open end overhangs as shown the funnel 6 at the upper end of pipe 2a. A suitable vertical slot 9a is provided at the overflow .end of the reservoir 8, the opening or width of the slot being adjustable and a preferred means for effecting such an adjustment (see Fig. 2) is to have an adjustable plate 9D adapted to Specification of Letters Patent.

have its position regulated by suitable backing screws '9C which screws may be threaded through a rib 9d on the reservoir.

ll is a tilting chemical feed box or holder which is suitably pivoted at l0'd1 to a cross piece 10lo supported on the I-beams 2b and so arranged that its open end also overhangs the outer edge of funnel 62 l0C is a cross piece also supported on the I-beams 2b and which acts as a stop for the tilting box 1IEL in its lowest or horizontal position. This tilting chemical box has an opening or slot l2a in its end overhanging the funnel 6ct the arrangement being such that upon the tilting of the box Il, the contents thereof are emptied more or less rapidly according to the amount of tilting, through the slot 12CL into the funnel 6u and central pipe 2a. This slot 12a is preferably made adjustable as shown in Fig. 3, and consists of similar means as that for the reservoir in being provided with an adjustable plate 13 adapted to have itS position regulated by suitable locking screws 145L which screws may be threaded through a rib l5 on the box. Another opening or slot 16a is formed in the end of the chemical box l la opposite the slot l20L for the purpose hereinafter explained.

Pivotally supported at I7ZL upon a suitable standard 17b is a leverl 18a, said lever having a pivoted connection at 19L at its remote end to the rod 2()a of a float 201. Said float may be guided ina perforated cylinder 2lLL suitably arranged in the reservoir 8a. The lever 1S@L has a connection at 22a with the tilting chemical box l la at a point opposite the pivot l()EL orapproximately so. A chemical feed pipe 24a is arranged to deliver into the chemical box 11, Bya forcing device (not shown) or other means a constant flow of chemical is fed through the pipe 24a somewhat iir excess of what is normally required for treating the water as supplie by the pipo 7a. chemical return pipe 23, which may have a funnel at its top is arranged directly underneath the opening or slot 16a.

The operation of the device will be readily understood from the foregoing description. When the pipe 7L delivers a larger quantity of water than usual, the water level in the reservoir 8'LL rises thereby lifting the float 20a. This float by the connections 19",l and 22a with the chemical box ll'LL will cause said box to be tilted to a greater extent, thus emptying a correspondingly larger proportion of the chemical therein into the funnel 6a to mix with the water from the reservoir 8a to be purified and permitting a smaller proportion of chemical to return by the opening or slot 16a and pipe 23a.

When the volume of water supplied by pipe 7a falls below normal the reverse operation takes place, the box 11aL assuming more nearly a horizontal position and hence a larger proportion of chemical will be discharged by slot or opening 16a into the return pipe 23il and a smaller amount will be added to the water flowing into funnel 6a,

The adjustability of the openings or slots l2a and QiL respectively in the chemical box 11LL and reservoir Sa, enables me to change within wide limits, or preserve a predetermined ratio between the water and chemical fed thereto.

The lever 18*L may be provided with a suitable counterweight 25a, if desired, to facilitate tilting of the box llt.- The perforate cylinder 2].a serves as a guide for the Vfloat 20EL and also prevents too sudden fluctuations of the float by throttling the ingress of water thereto.
